AThis invention reiatesto ar'tvcanvas and a method and means o`f restoring the same and is a continuation in part of my co-pendingappli cation Serial No. 182,602, nfor Met'ali'zed Art Canvas, filed August 3l, 1950, nowabandoned.

An object of this invention is to Vprovide surface 'for art painting which will resist deterioration with time, and which will retain its iiexible characteristics indefinitely. n

Another object of this invention is to .provide a flexible sheet 4which 'may be amalgamated with an old art canvas so as to sustain the old and deteriorated canvas and permit the normal hanging ofthe old painting.

A further "object 'of this invention is to provide an improved basic compound or preparation which may be mixed with various ingredients to provide the desired `paint receiving base having a eXible characteristic so that vit will not become brittle and crack witnage.

-In the carrying out of this invention 'a copper wire mesh is used as 'a -base and Athe mesh is rolled or otherwise attened so as to eliminate the bumps normally 'caused by the crossed fand woven wires and to obtain 'a 'sin'oth surface without the use of mineral fabric'. The interstces of the mesh are entirely closed or left in a porous condition depending on the use by an artist or an art restorer.

Another object of this invention is to provide a painting surface which will not be subject to the expansion and contraction characteristics of a conventional brous canvas, so that the paint forming the art subject will not crack, shell, flake or chip.

With the above and other objects in view, my invention consists in the arrangement, combination and details of construction disclosed in the drawings and specication, and then more particularly pointed out in the appended claims.

In the drawing:

Figure 1 is a fragmentary plan view of a metalized art canvas constructed according to an embodiment of this invention.

Figure 2 is a fragmentary sectional view taken on the line 2--2 of Figure 1.

Figure 3 is a fragmentary sectional view of a modified form of this invention.

In the formation of a metalized art canvas according to this invention a copper screen I of suitable mesh is stretched over a frame, and preferably the screen I0 is passed through rollers `so as to flatten the mesh as much as possible. The screen I0 is then given an initial coating ll of a nller composition which also serves as a fabric (C1. ii-'32) 2 bond-ing means- The ffill'er composition is formed of the following:

Parts 5 Graphite 5 Vehicle v 1 Graph-ite is defined as plumbago or a mineral carbon.

The vehicle used with :graphite isproduced from the following, in substantially the proportionsin-v dicated:

371/2 lbs. of inner tube rubber (natural rubber). 371@ lbs. of inner tube rubber (synthetic rubber). T5 lbs. rosin.

One example of' synthetic rubber is that having a Buna S base and which comprises a butadienestyrene copolymer type synthetic rubber. YSyn-- thetic rubber having other bases may also be used.

1 gal. gastar liquid. l'galwater. 1 gal. mineral spirits.

.The gastar liquid is a residue obtained from the manufacture of illuminating gas from bituminous coal. The base of gastar is creosote. One example of mineral spirits is kerosene, or a low grade of gasoline.

The vehicle is formed by cutting up the natural and synthetic rubber into relatively small pieces and then placing the above rubber ingredients including rosin into a container Where the mixture is subject to heat at a temperature of from 220 to 240 F. for a period of two hours. After being subjected to heat of from 220 to 240 F. for two hours, the temperature is raised to 350 to 400 F. for a period of one half hour. During the initial cooking of the mass, the gastar is left out, but is poured into the hot mass in the final high temperature period and serves to break up the synthetic rubber before the latter carbonizes. The heated liquid mass which now equals about 13 gallons is placed into a 55 gallon barrel, and the latter is then lled with mineral spirits and left to settle for 30 days. The free carbon will settle out, and the liquid, which is herein termed vehicle, will be drawn off of the carbon.

Before the ller coating has completely dried on the screen a mineral fabric l2, such as glass fabric, is laid over the screen so as to effectively adhere to the screen. After the mineral fabric I2, such as glass fabric l0, is secured by tacking over the copper screen, and the fillers are applied through the screens with a gun or brush, addi- 1 part lacquer.

1 part lacquer thinner.

1 part raw linseed oil.

1 part vehicle as described supra.

Per cent White lead 60 Zinc oxide 30 Vehicle (supra) 10 A brush coating I4 is then placed over the White coating and is formed as follows:

Cement (white Portland) lbs 4 Vehicle (supra) pints 7 Art paint I5 may then be applied to the surface of the brush coating.

'Where an old and damaged painting I6 is to be restored, the back I1 of the painting I6 is laid against the restorer canvas and a coating H of the filler in soft and substantially fluid state is applied to the porous canvas. The filler I is applied to the screen l I from the back of the latter so that the ller will flow through and close the interstices of the screen Il and at the same time amalgamate with the canvas of the painting I6. Drying of the filler will effect an adherence or amalgamation of the painting to the metalized canvas. In this manner the canvas 4 of the old painting will be reinforced by the metalized backing which will prevent cracking or tearing of the old canvas.

I do not mean to confine myself to the exact details of construction herein disclosed, but claim all variations falling within the purview of the appended claims.

What is claimed is:

l. A metalized canvas comprising a wire screen, a glass fabric, a combined filler and adhesive means impregnating said fabric and said screen.

-said filler being formed of graphite, a vehicle, and

a surface coating on said fabric.

2. A metalized canvas comprising a Wire screen, a glass fabric, a combined filler and adhesive means impregnating said fabric and said screen, said filler being formed of iive parts graphite, one part vehicle, and a surface coating on said fabric.

3. A metalized canvas comprising a wire screen, a glass fabric, a combined filler and adhesive means impregnating said fabric and said screen, and a surface coating on said fabric, said surface coating being formed of White lead, zinc oxide and a vehicle.

4. A metalized canvas comprising a wire screen, a glass fabric, a combined filler and adhesive means impregnating said fabric and said screen, and a surface coating on said fabric, said surface coating being formed of six parts white lead, four parts zinc oxide, and one part vehicle.
